Jeena emailed me recently about his Rails plugin, plistifier, that allows you to render plists (property lists).

It allows you to render your ActiveRecord objects as plists (among other things):

def show
  @post = Post.find(params[:id])

respond_to do |format| format.xml { render :xml => @post } format.plist { render :plist => @post } end end

Jeena was kind enough to let me know he "stole" my old Jsonifier plugin (github) code in plistifier.
